TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 511,374, dated December26, 1893.

Application filed May 27. 1893. Serial No. 475,753. (No model.)

To all whom it may concern:

Be it known that I, CHARLES FAYETTE TAY- LOR, a citizen of the UnitedStates, and a resident of New York city, in the county of New York andState of New York, have invented certain new and useful Improvement inType- Writing Machines, of which the following is a specification.

My invention relates to that class of type writing machines employing aninking ribbon, and has for its main objects to provide simple andefficient means for automatically moving the ribbon widthwise, and alsofor antomatically reversing the longitudinal movement of the ribbon.

To these ends myinvention consists in the various features ofconstruction and combinations of devices hereinafter morefully.described and particularly pointed out in the appended claims.

In the accompanying drawings,Figure l is a top plan view of a portion ofa type writing machine showing some of my improvements. Fig. 2 is avertical section thereof taken at the upper portion of the machine, andat the line 00, as of Fig. 1. Fig. 3 is a rear elevation of the machine.Fig. 4 is an enlarged detail view, looking from the front of themachine,

of some of the devices employed to reverse the movement of theribbon,and also to move the same widthwise. Fig. 5 is an enlarged detailview, looking from the front of the ma chine, of a portion of thecarriage driving arm and one set of the devices thereon employed toactuate the ribbon reversing levers, the pin or projection on one ofsaid levers being also shown. Fig. 6 is an enlarged vertical section toillustrate the construction and operation of the parts employed inconnection with the reversal of the ribbon. Fig. 7 is a plan view of theribbon-carrier and the crank or eccentric for moving the same, andshowing also a portion of the ribbon. Fig. 8 is a diagram to show themanner in which the ribbon is used, or the lines upon which it is struckby the types atdifferent times. Fig. 9 is a detail view, in frontelevation, of the means for supporting the forward end of the ribboncarrier; and Fig. 10 is a vertical.

section taken at the line (1 y of Fig. 1.

In the several views the same parts will be with the gear 13.

found designated by the same numerals and letters of reference.

I have shown my present improvements carried out in that form ofmachines known as the Oaligraph, but since they may be embodiedin otherstyles or constructions of machines, I do not of course wish to beconfined thereto.

The mechanism for reversing the ribbon 6o automatically herein shown andto be described is the joint invention of myself and Harold P. Brown,and is set forth and claimed in another application filed simultaneouslyherewith by myself and said Harold P. Brown. In this case, therefore, Iintend to cover said mechanism only in so far as it relates to orco-operates with the means which I personally have devised forautomatically moving the ribbon widthwise.

1 designates the top-plate or type-ring, 2 the paper carriage, 3 thespring-actuated driving arm therefor, 4 the carriage feed-rack, 5 thefeed-dog, and 6 the front supporting rail or track for thepaper-carriage.

The inking ribbon 7 is connected at one end to a spool 8 at the lefthand side of the machine (considered from the front), and at its otherend to another spool 9 at the right hand side of the machine, each ofsaid spools being mounted upon and adapted to rotate with a shaft 10.The ribbon passes from one of said spools upwardly and inwardly over aguide and support 11, and'thence horizontally across the machineunder-the platen 12, to and over another guide and support 11 and thendownwardly and outwardly to the other spool. At the rear end of eachspool shaft 10 is secured a bevel gear 13, with which a bevel gear 14 ona counter-shaft 15' is adapted at certain go times to engage. The saidgear 14 is adapted to slide longitudinally on the shaft 15, and also torotate therewith, a fork 16 connected to a switch or shifter 17 beingprovided to slide the gear 1e into and out of engagement 9 5 The shaft15 is turned step-by-step by a pawl-and-ratchet-mechanism, there beingupon said shaft at its inner end a ratchet wheel 18, with which engagesa driving pawl 19, mounted upon an arm 20, :00

extending from a rocker 21 near the base of the machine and connected asusual to the universal-bar, which overlies the key-levers. (Not shown.)The arms are preferably connected together at their upper ends by ahorizontal bar 22, which carries the feed-dog.

The shifter 17 is slotted at its ends and supported by screws 23. Whensaid shifter is moved toward the right the fork 16 at the right handside thereof moves the right hand gear 14 into engagement with itsassociated gear 13, and thereafter at each forward movement of the arm20 the spool 9 will be partially rotated and the ribbon wound thereupon.Upon such movement of the shifter toward the right the left hand gear 14is simultaneously disengaged from its companion gear 13, and the ribbonspool 8 and its shaft are left free to pay off the ribbon on said spoolin accordance with the pull or winding action of the spool 9. WVhen thesaid shifter is moved in the opposite direction or toward the left theright hand gears 13 and 14 are disengaged and the left hand gears 13 and14 are re-engaged and thereafter during the operation of the machine theribbon is wound step by step back upon the spool 8 again. This mechanismfor moving the ribbon longitudinally from one spool to another and thenreversing it, by a hand movement of the switch 17, will be found morefully set forth in the Letters Patent granted to Fairfield and FrancisFebruary 4, 1890, No. 420,790. In connection with this mechanism I haveshown my novel means for automatically moving the ribbon widthwise, butit will of course be understood that my improvements, now to bedescribed, may be used in conjunction with other means for moving theribbon longitudinally.

About centrally of the machine widthwise is arranged a ribbon carrier24, which is adapted to be moved back and forth step by step in adirection practically at right angles to the longitudinal movement ofthe ribbon and to carry said ribbon in its said movements. Said ribboncarrier consists preferably of a frame 25, a shank 26, projectingrearwardly therefrom, and a tongue 27 projecting forwardly therefrom.The frame portion is provided centrally with a large opening, as at 28,for the passage therethrough of the types, and near each end of saidopening is a transverse bar 29. In putting the ribbon in place upon themachine one end thereof is first passed under one end of the frame 25,then over one of the bars 29, then over the opening 28, and over theother bar 29, and then down under the opposite end of the frame 25, asshown at Figs. 1 and 10. By thus threading the ribbon or connecting itto the ribboncarrier, the latter when reciprocated is adapted to carrythe ribbon with it. The tongue 27 is provided with a slot 30 whichembraces a guide pin 31 depending from the under side of the rail ortrack 6. A flat spring or narrow springy plate 32 having an upwardtendency is fastened by a screw 33 to the under side of the track 6 andextends longitudinally thereof in a manner to form a support for saidtongue and hence for the front end of the ribbon-carrier. One end of thespring 32 is provided with a finger-piece 34 to enable the spring to beconveniently depressed when it may be desired to remove or displace theribbon-carrier for the purpose of cleaning the type, making adjustments,&c.

The shank 26 of the ribbon-carrier is pivotally connected to a crank orwrist pin 35 on a crank or eccentric 36, which is mounted fast on theupper end of a vertical shaft 37, which has a hearing at its upper endin a bracket 38, and bearings at its lower end in brackets 39, securedto an upright plate or support 40, preferably cast integral with theframe work of the machine. Upon the shaft 37 at its lower end ishorizontally arranged a crown ratchetwheel 41, the supporting plate 40having an opening 42 for the accommodation of said ratchet wheel. A pawl43 is adapted to engage with the teeth of said ratchet wheel to turn theshaft 37 intermittently and to effect through the crank and the ribboncarrier step-by-step widthwise movements of the ribbon.

The pawl 43 is preferably pivoted upon a lever 44 which is pivoted at 45upon the plate 40, and which is provided with a spring 46 and two pins47 and 48, the former being at the upper portion of the leverand thelatter at the lower portion thereof, and working in an arc-shaped slot49 in the plate 40. The uppermost end of the lever 44 is arranged toco-operate with a pin 50 extending rearwardly from the shifter 17, andat certain times, as will be presently explained, move said shiftertoward the left to automatically reverse the direction of movement ofthe ribbon.

Pivoted at 51 on the plate 40 is a lever 52 having a notch or shoulder53 to engage with the pin 48 of the lever 44 and lock or hold said leveragainst the tension of its spring 46. The outer end of the lever 52 isoperatively connected to the ribbon spool 8 by means of a chain orflexible connection 54 and plate 55. The plate 55 is guided in a slot 56in a bracket 57 having a ledge 58, and said plate is provided with arest 59 and a perforation or opening 60. Normally the rest 59 bears uponthe bracket 57, and the upper portion of the plate 55 has a tendency tolean always toward the ribbon spool shaft. A screw 61 is passed throughthe ribbon spool 8 and engages a longitudinal groove in the ribbon spoolshaft. The head of said screw projects, and when the ribbon is unwoundfrom said spool, said head engages the opening in the plate and, by thecontinued rotation of said spool, lifts the same and the latch lever 52.When said latch leverislifted the shoulder 53 is raised from the pin 48,andthe lever 44 is released and vibrated by its spring 46, the upper endof the lever moving toward the left and causing the shifter to slide inthe same direction and reverse the engagement of the two pairs of gears13 and 14, in a manner such 7 70, having an extension 71.

that thereafter the ribbon will wind back upon the spool 8.. r i.

In order to automatically move the shifter toward the right when thespool 9 becomes,

empty, a lever 62 is pivoted at 63 upon the plate 40, and is provided atits lower end with two pins 64 and 65. The said lever 62 is alsoprovided with a spring 66 and its uppermost end is adapted to.co-operate with a pin 67 projecting rearwardly from the shifter 17.Means precisely like those just described with reference to the lever 44are provided to lock or hold the lever 62 and to release the same whenthe spool 9 becomes empty; that is to say, there is provided a latchlever, as 52, a chain, as 54, a lifting plate, as 55, and a projectionas 61 on the spool for raising said plate. Hence, when the ribbon hasunwound from the spool 9, the latch lever is raised to unlock the lever62, the latter is vibrated by its spring and the shifter is moved towardthe right to change the engagement of the driving gears.

To provide a practicable contrivance, it is apparent that some meansmust be provided to reset or re-lock the levers 44 and 62 after theirrespective operations upon the shifter, and for this purpose suitabledevices are mounted on the carriage driving arm 3, which devicesco-operate with the pins 47 and 64 on the levers 54 and 62,respectively, during certain movements of the paper-carriage andcarriage driving arm toward the right.

The devices for re-setting or re-latching each of the spring actuatedshifter levers are similarly constructed and operate in substantiallythe same manner.

1 shall now refer to that group of devices which is employed to re-setthe lever 44. On the inner face of the driving arm is a block 68 towhich is pivoted at 69 a pawl or driver On the left hand side of theblock is pivoted at 72 about lever 73, which is weighted, as at 74, atits lower end, and is adapted to work upon the extension 71 in such amanner as to maintain the pawl always in such a position that it willengage with the pin 47, when the lever 44 has been released, and duringthe sweep of the driving arm toward the right.

By referring more particularly to Fig. 5, the re-setting operation willbe more readily understood. In that view the lever 44 is supposed tohave been released and its pin 47 thrown up in the are a into the pathof the point of the pawl 70 which normally travels in the are I). When,however, the pin 47 isin the position shown at said figure, and thepoint of the pawl in moving to the right strikes the same, the pawl isfirst independently vibrated about its own pivot until its rear edgestrikes against a stop or pin 75 proj ecting from the block. Thereafter,the point of the pawl, during its engagement with the pin 47, travels inthe arc c. When the independent vibration of the pawl has been arrestedby the stop 75 the pin 47 is acted upon the small circle 6.

positively and driven by said pawl during the continued sweep of the arm3 toward the right, due to the pull upon the carriage by the arm of theoperator, and the lever 44 is vibrated, as the pin 47 is forced down inthe are a, until the pin 48 on the lever 44 is brought into alignmentwith the notch 53 of the latch lever, when the latter at once descendsand effects a locking of the lever 44 against the tension of itsspring.- During this re-latching of the lever 44, the driving pawl 43thereon is moved forward a tooth or step on the crown ratchet wheel andturns the latter, its shaft, and the crank 36, and through the latterthe ribbon carrier and ribbon are moved one step or a slight distance ina direction widthwise of the ribbon. When this has been accomplished thetypes will use the ribbon in a new or fresh line longitudinally of theribbon. Inasmuch as the pawl 43 turns the crown ratchet Wheel 41 onlywhen the ribbon begins to wind upon the spool Sit will be seen that theribbon is used in one line only lengthwise while traveling from thespool 9 to the spool 8 and back again; or,in other words, the ribbon isshifted widthwise one step only during two of its longitudinalmovements, but of course if desired by the manufacturer, another pawlsimilar to 43 may be connected to the shifter lever 62 to move theribbon widthwise a step when said lever is re-set, thus providing for awidthwise movementof the ribbon for each longitudinal movement thereof.

By referring to Fig. 7, the small circle 61 may represent the printingpoint of the machine, and the line i; the vertical axis or lowermostportion of the platen which travels over or coincident with saidprinting point.

This line may also represent the line of impressions. As each typestrikes at the point at the ribbon is moved longitudinally during thestep-by-step spacing of the carriage in writing, and the ribbon is usedat this time lengthwise along the line 1), portions of said ribbon alongsaid line being successivelv brought coincident'with the printing point.At this time the crank and the ribbon-carrier are supposed to be in thepositions shown by the full lines at Fig. 7. In the course of time whenthe pawl 43 partially turns the ratchet wheel the crank is turned onestep in thedirection of the arrow at Fig. 7, and a fresh portion of theribbon will be moved rearwardly to register with the impression point.This portion may be represented by Thereafter the ribbon will be used ina line coincident with c.

-When the ribbon carrier is moved again a portion of the ribbonrepresented by the circlefls brought to register with the impressionpoint. Then the ribbon will be used longitudinally along the linecoinciding with f. Afterward when another movement of the carrier ismade the ribbon will be used along the line coinciding with g, and thenin like manner subsequently, along a line coincident with h. \Vhen theportion of the ribbon last mentioned is being used the crank has made ahalf revolution, and on the return stroke the ribbon is againsuccessively used on the parallel lines g, f and e, which will allsubstantially coincide with the parallel lines represented by g, f, anda. At Fig. 8, the lines represented by the small circles just abovereferred to, and on which the ribbon is used, are diagrammaticallyillustrated.

The re-latching of the lever 62 is effected by a set of devices on thedriving arm 3 arranged beneath the set of devices for re-latching thelever 44, and since they act upon the pin Get in precisely the samemanner no further description thereof appears to be necessary.

If the carriage driving arm should be on the right hand side whileeither lever 44 or 62 is in an unlatched condition, the pawl of eitherre-setting mechanism, on colliding with the pin 47 or 64 during thestep-by-step movement of the paper-carriage toward the left will tiltand ride over the same and then be righted by the weighted bent lever,after passing the pin.

At Figs.3 and l, the spring acting lever 44 is shown unlatched, and thespring acting lever 62 latched.

It will be seen that the ribbon carrier is arranged substantially atright angles to the longitudinal travel of the ribbon and guides andcontrols the ribbon at or in the vicinity of the impression point. Inother words, the ribbon is forced by said carrier to travel past theimpression point in a series of parallel lines determined by the variouspositions which the carrier is caused to occupy during the stepby-stepmovements of the crank, which, as explained, occur only at theconclusions of the longitudinal movements of the ribbon,or when theribbon is reversed to travel lengthwise in opposite directions. Thus bymeans of the centrally arranged carrier, the travel of the ribbon iscontrolled at the impression point irrespective of any movements of theribbon spools on their shafts and the ribbon is used practically for itsentire width in parallel lines running longitudinally of the ribbon. Itwill also be seen that by my invention the ribbon is moved widthwisestep-by-step, by means wholly disconnected from the finger key action,and hence the fingers of the operator are relieved from performing anyextra duty. As the widthwise movements of the carriage are effectedthrough the movements of the cat;- riage toward the right, which aremade always by the arm of the operator, the power necessary to efiectsuch ribbon movements is wholly imperceptible, and as during the returnmovement of the carriage there is such an abundance of surplus power,the force required to re-set either one of the shifter levers is notlikewise felt or appreciated by the operator. The shifter levers arealternately re-set only at the completion of a longitudinal movement ofthe ribbon, and hence while the ribbon is I moving lengthwise betweenshifts the resetting devices pass said levers inoperatively during theback and forth sweeps or movements of the carriage driving arm.

Various changes in detail construction and arrangement may be madewithout departing from the gist of my invention, and I do not wish to belimited to the use at one time of allot the mechanisms shown, as somemay be employed without others.
